Abstract

This paper increases the splitting ratio of 10 Gb/s-class passive optical
network (PON) systems by using a novel low-loss optical splitter based on
single-mode (SM) to multimode (MM) coupling. It consists of a planar lightwave
circuit (PLC)-based funnel-shaped waveguide (FW) and a dual-mode fiber (DMF)
that supports both SM and MM propagation through its dual core configuration.
While conventional low-loss splitters based on a similar principle, called mode
couplers or mode combiners (MCs), pass through only upstream signals, the
proposed FW-DMF acts as a low-loss splitter for upstream and a conventional
splitter for downstream despite its simple configuration. Compared to
conventional MCs, it greatly reduces the number of optical components required
for an optical line terminal. Considering the more efficient use of existing
infrastructures, we develop two types of FW-DMFs with branching ratios of 4 and
16. Bit error rate measurements assuming 10 G-EPON systems show the ability of
our prototypes to realize 128-split 10 Gb/s-class PON systems.
